不同株高玉米配置对玉豆复合种植模式下玉米光合特性及产量的影响
Effects of Different Plant Height Configurations on Photosynthetic Characteristics and Yield of Corn under Corn-Soybean Complex Planting Pattern
摘要
Abstract
In order to fully explore the yield potential of corn in the corn-soybean complex planting pat-tern,and to improve the yield of the complex planting system,this study selected 12 corn varieties with differ-ent plant heights and shapes under the intercropping pattern of corn and soybean with row ratio of 4∶4.Two ex-periments with different plant-height configuration were set up:one with different short-stalked varieties in the side rows(Liyuan 296 in the middle rows)and the other with different high-stalked varieties in the middle rows(Golden Grain MY73 in the side rows),which were labeled as side row(B)test and middle row(M)test.The effects of different plant height configurations on the photosynthetic characteristics and yield of inter-cropped corn were researched systematically.The results showed that in B test,the leaf area index and photo-synthetic performance of Denghai 605 and Ludan 608 were significantly better than those of other varieties,and they had small impacts on growth and development of Liyuan 296 in the middle rows.The population light energy utilization rate was high,and the total yield of the combination was significantly higher than that of oth-er variety combinations.In M test,Liyuan 296 and Nongda 372 were less affected by Golden Grain MY73 in the side rows with higher population light energy utilization rate,and the total yield of the combination was sig-nificantly higher than that of other variety combinations.In summary,under the conditions of this experiment,the combination with Denghai 605 and Ludan 608 as the side-row varieties and Liyuan 296 as middle-row vari-ety,and the combination with Liyuan 296 and Nongda 372 as middle-row varieties and Golden Grain MY73 as side-row variety had better photosynthetic performance and higher yields,which could be promoted in the pro-duction.关键词
